To allwkomitmag concern. H

Be it known that LCmuxo'n Game, a

- citizen of the Bridge, in the county of Burlesonand State of Texas, have invented certain new and useful Improvements in Machine-Guns, of

" which the following is a specification This invention relates to improvements in machine gunsand it is the {wind al object of the invention to provide a mac ine gun so constructed as to rmitthe simultaneous discharge ofa plura ity of cartridges therein, and the projection of the bullets therefrom in a mannersuch' as will cause the same to effectually sweep. the path of travel thereof.

'Another and equally important object of the. invention isto provide novel means for effecting the simultaneous discharge of the cartridges arranged in the gun, the same bein automatically operated.

. t is also an object of the invention to provide a novel form of magazine for the gun, whereby the cartridges will be properly fed into the breech portions of the various barthe gun, the magazine beingraisied in ate by step fashion and. the cartrid es carri to positions in alinement with he bares of'the gun barrele. Other independent objects are to provide lcifeatures-of construction'of portions of the .5 n, which tend towardtheattainment of t e above aimsi which the are Other jects wili be in ie obvious and n tive of the relation in is in a pointedouthereinafter. 3

' he. invention accordingly consists in the features of construction; combinations of 'elemeiita and arrangement of parts which will be exemplified in the construction here; 40 ina'fter set forth; and the scope of the ap lication of. which willlbeindicated in the 01- p -lowi.n;hc1aims. p

I Fig; 6 is a dia rammatic view showing the manner in whic the various firing pins of the gun are actuated, and a Fig. 7 is a fragmental detail of the gun shield. I Similar reference characters refer to similar parts throughout the several views of the:

e subsequently apparent. A gun barrel support 3 is pivotally supported between the upper ends of the standards 2, suitable'bearing pintlesbeing engaged in the apertured upper .ends o'f.said standards. In this connection, it is to be noted that the outer marginal portion ofthe support 3 is convex,

while a pluralitv of radially disposed open ings are form in the same and receives plurality of gun barrels 4 therein.

The frame-comprising oppositely disposed side pieces 5 and a bottom 6 is provided, the side pieces having metal strips 7 arranged adjacent the outer faces thereof, certain of the ends of said strips being bent at substantially right angles as at .8 to engage the :adjacent mar 'nal portions of the sides;

Ways 10 are ormed in the adjacent faces of the side pieces5 and extend longitudi- 'nally of the same, ser'vingas means for slidably retaining a magazine 11, which as will be noted includes a substantially recta ula-r frame having a pluralit of cartri ge receiving and supporting rac .s 12 extending transversely therethrongh and having their opposite ends securely engaged with the ad[ acent sides of said frame. Ratchet mem 1 ers 13 are secured to the adjacent or inner "faces of the side pieces 5 by a suitable means and are adapted tohe engaged by a spring pressed paw 14 suitably mounted upon the lower end of the magazine 11.

As means for raising the magazine 11 in order that the various cartridge retaining racks12 may be alined with the breech por-' tions of the various barrels 4, a ratchet bar 15 having'an otf-set 11 per end 16 is passed through an opening 1 formed in the bottom piece 6 of the frame into pivotal enagement with a lever 18 as at 19, the said I- ever, as will be noted, being pivotally engaged with the bracket arm secured to the for a purpose which willJlL forward end of the bottom piece 6 and designated by the numeral 20., A-guide, 2-1 is assed through'afn olpening formed in the o -st portion 16 of t bar l5. into em 6 gagement with the adjacent portion of th frame and has a contractile Spring'QB 'ar ra rea a y the ratchet bar will be normally drawnin a 10 direction toward the magazine 11 and hence,- the ratchet teeth formed therc'on will be coir" stantlyengaged with an adjacent portion of said magazine 11. Rotatably mounted on the bottom ieee (i isa crank'shaft'23 hav- 13 ing one en with an arm 24, which arm in turn is pi\.0t

ally engaged with a second arm baiting its remaining end pivotallyconnected to the outer end of the lever l8as {11:26. T hus, by 20 rocking the crank shaft 23 'veitical'm'o vement will be imparted to the ratchet bar. 15 and as a 'consequenee the magazine 11f will be raised in the frame of tlie inachine' gunfin a ste by step fashion; the pawls' 14; engag- 2 5. ingtiie various ratchet pieces 13 and'serv'ing as ineans for supporting the same -in its'adjusted position.-

. the bottom piece 6 of the inachinegun frame to is an internally screw threaded collar QZ which rebeives one end of a screw threaded Shaft 28:. therethrough, the outer end of said 7 shaft passing through j the second pivot'ally supported internally-"screw threaded collar 35. 29 and having acrankhandle 3O pivots-11y mounted thereon. Obviously, by f'rotating i the screw-threaded she [t 28 the maehine 'gun frame,- which is ivotallysupported upon I thei upperends 0? the *vertical standards 2 4o will be 'jswu-ng to a position :such as willper- Unit the varying of the range of the gun.

Inasmuch, as t e barrel support 3 is 'neet'ed to'the frame, it of course will be un- 'derstood that the various barrels 4 will be 'moved in a direction corresponding t'othe movement of the magazine 11 and; as a-consequence, thefeeding' of cartridges into" the I breech portions of said barrels willbe atjill tunes permitted, irrespective of 'thefl'adju's't- Inent of the same.
